Serial Port Visa to read 1 line of IO

[QRP]

I have a serial visa opened and need to read the status of pin-6 on a 9-pin serial connector to see if that line is high or low. Is there a way to do this by the serial visa read command?

Pin 5 is ground on a 9 pin connector. If you want to detect actual input lines such as CTS, DSR, DCD, or RI, use a VISA property node and Select Property>Serial Settings>Modem Line Settings

Thank you so much. I meant pin 6 😃
